CARBURETER.

Application sied Deeember 22,1906. seriel Ne. 349,016.

To all 'whom it may concern:

Be it known that I, EDWIN J. SELLEY, of the city, county, and State of New York, have invented a new and Improved Carbureter, of which the following is a full, clear, and exact description.

My invention relates to improvements in carbureters, and theobject of my invention is to producea device of this character which is of the utmost simplicity, which is very compact in form, and which is adapted for a variety of uses, such as supplying carbureted air to burners for lighting purposes, or to internal combustion or explosive engines such as are used on automobiles and in marine and other work.

A further object of my invention is to produce a structure which will thoroughly charge the air with nebulized carbonaceous matter and the invention is also intended to provide a convenient means for mingling more or less air with the carbureted material as it is brought through the service pipe to the end that the best ignition may be had. In carrying out this idea, the regulating or Bunsen valve can be located at any point between the mixing chamber and the point of ignition, and can be nicely controlled so that if this gas is very rich, more air can be admitted, or the supply of air can be graduated nicely according to the richness of the gasitied fuel.

With these ends in view, my invention consists of certain features of construction and `combinations of parts which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure l is a broken sectional elevation of the complete apparatus, and Fig. 2 is a detail showing a means for operating the regulatinglvalve.

The apparatus consists of a tank 10 which can be of any suitable kind, and extending downward into the top of the tank is a removablepipe l1 which can be screwed into the tank, or can be fastened in any convenient way, and this pipe is open near the bottom and the openings are provided withV strainers 12, to prevent dirt from getting into the nebulizer pipe 14. On the top of the tank l0 is a mixing chamber 13 which can be of any approved form, but which is preferably `spherical so that it can be adjusted conveniently on the tank l0, and it will be seen that when the parts are to be separated, the mixing chamber 13 can be lifted bodily from the tank 10, and the pipe l1, which is attached to the part 13, withdrawn with the mixing chamber.

Specication of Letters Patent.

Patented Aug. 2o, 1907.

The nebulizer pipe 14 extends downward into the pipe 1l to a point near the bottom, so that the gasolene or other fuel will always be drawn from the point where it is heaviest, and the pipe 14 can be stayed in any convenient way, as by a spider l5. An elbow coupling 16 connects the top of the pipe 14 with the pipe 17 which discharges air under pressure directly across the top of the pipe 14, and which thus sucks up the fuel and nebulizes it so as to mingle it with the air in the mixing I chamber 13. The air to supply the pipe 17 is drawn from a source of supply 18, which can be a compressor, air pump, tank, or any suitable source, and the supply is controlled by the valve 19. The service pipe 2O and its extension 21 leads from the'mixing chamber 13, and

this has a regulating valve 22, which regulates the sup- -ply of air to the pipe 21. The valve can be of any usual form of regulating valve, like the valve of a Bunsen burner, but it has preferably a rotary part to control the gas and air supply, and this part can be operated in any convenient Way, as by hand, but preferably by some mechanism so that a system of levers can connect it to a point within reach of the driver of the automobile. I have not shown this lever system, because anything for the purpose can be used.

The rotary part 23 I have shown provided with a gear 24, and it is mounted in the frame 25 connecting the pipes 2O and 21. The rack 26 meshes with the gear 24 and connects with a lever 27, which can be operated in any convenient way to slide the rack and turn the gear and the valve part 23. I have shown this mechanism simply to illustrate a means of operating the valve, but this invention does not relate to the valve structure, but comprises in part any suitable valve which will provide for admitting more air if desired, to the service pipe.

From the foregoing description it will be seen that the carbureter which I have shown is extremely simple, that it can be put together or taken apart very readily, and that it serves the purpose admirably of carbureting any necessary quantity of air.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An apparatus of the kind described, comprising a tank to contain liquid fuel, a mixing chamber resting on 'and separable from the tank, a pipe extending from the mixing chamber into the tank to a point near the bottom of the latter, and a nebulizer connected with the source of forced air supply and arranged to draw from within the lower part of the aforesaid pipe.

2. An apparatus of the kind described, comprising a fuel tank, a mixing chamber resting directly on the tank and provided with a pipe which extends downward into and can be lifted from the tank, a nebuiizing pipe extending downward into the first pipe, and an air pipe discharging across the top of the nebulizing pipe.

3. Anv apparatus of the kind described, comprising a fuel tank, a mixing chamber resting on and detachable from the tank, a pipe with openings therein secured to and extending from the mixing chamber downward to u point near the tank bottom, and a nebulizing device comprising a pipe extending downward into the rst mentioned pipe, 10 an air pipe connecting with a source of air snppiy and extending across the second pipe, and means for supporting the ends of the second pipe and the air pipe in juxtaposition. y
